Open hotspot mobile phone card on iPhone8plus

The iPhone 8plus turns on the hotspot phone card, mainly due to the following situations:

(1) System problems. If the system version is relatively low, there may be some bugs in the old system. The repair or business functions are not optimized, causing the phone to freeze when using APP and other applications. It is recommended to update to the latest iOS system.

(2) Memory problem. If the memory is relatively small, it will take up a lot of memory when running some large mobile games or APPs. Insufficient memory may cause lags. It is recommended to close background applications. Or use it according to the mobile phone configuration.

(3) Cache problem. Long-term use of mobile phones will generate a large number of application caches, such as WeChat, QQ, Weibo, etc. It is recommended to clean or delete the APP regularly and reinstall it.

(4) For setting issues, you can enter General, turn off some effect settings, or turn off some of the system's built-in applications, such as the Siri service.

(5) Network problem, it is recommended to use WIFI or 4G network.

(6) If the card suddenly occurs, it is recommended to restart the phone and try again. If the problem still cannot be solved after restarting the phone, you can restore the factory settings (it is recommended to back up before proceeding). If the phone still cannot reach the expected status after troubleshooting the above conditions, it is recommended to go to an after-sales outlet for testing or choose to purchase another suitable iPhone for use based on personal financial conditions.
